I Finally got the chance to ride my new 05 WR450. After spending some quality time with it in the garage doing all the mods, which is a piece of cake i might add, gray wire, air box, JD jetting (spot on) Ty fuel screw, powernow (both which i recommend) pro circuit 496 pipe (fits nice works great and sounds good too, not to loud) and the lowedogs ais kit (another nice piece and easy to do) This things runs great !!!! Everything i needed to do was on here you guys are great. I sure hope i run into some TTers when I'm out riding. I must say after my first ride (up in Georgetown) this past weekend i gotta say this is the best Dirt bike i have ever owned, and Ive owned a few. Just Sold a wr250 to get the WR450 and i couldn't be happier. Wanted more power, got it, wanted e start, got it didn't want a heavy tank of a bike, didn't get it, (had a drz 400, nice but heavy) I'm sure once i get used to this bike i will be able to toss it around like i did the 250. some guys on here where talking about throttle controll, well of course you have to controll the throttle its a "450" for crying out loud this things gots lots of power use it right and never run out. I love how you can point this thing into a corner, hit the gas and rail out like its on cruise control even in the tight stuff. and jumps well i don't have it tottally dialed in yet but it sure feels like I'm landing on a marshmallow. I'm 210 lbs 6' 2' so will stiffen it up a bit but not until i need to right out of the box its working great. Thats my story and I'm sticking to it..... Happy riding guys and thanks for the help.
